STORING APPARATUS FOR EXHAUST-STEAM, HEAT.

Application filed May 27, 1913. Serial No. 770,174.

To all whom it may concern:

Be it known that I, CURT SCHRAEILER, residing at Essen-on-the-Ruhr, Germany, I a subject of the Emperor of Germany, have invented a certainnew and useful Improvement in Storing Apparatus for Exhaust- Steam Heat, of which the following is a specification.

This invention relates to storing apparatus for exhaust steam heat with floating bell,

and its object is to provide a heat storing. apparatus of this kind of simple construe-- tion, having large coolingand reevaporat= lug-surfaces, wherein the fluid, which serves as heat absorber, is' automatically circulated by the steam pressure, making a special pump unnecessary.

Two embodiments of the present inven tion are illustrated in the accompanying drawings, wherein Figure 1 shows one of the embodiments in a vertical section along the longitudinal axis, and Fig. 2 a similar view of the second embodiment of the invention.

Referring first to Fig. 1, which represents a heat storing apparatus constructed as a gas-meter, this device consists principally of a stationary tank A partly filled with water B, which servesas heat absorber, and a floating bell C guided inthe tank A. An oilseal D covers the part of the water bath B which is situated between the inner cylindrical surface of the tankA and the outer cylindrical surface of the floating bell C. A branch pipe 6 leads from the main E of the exhaust steam into the tank A. This branch pipe opens into a tube F, suspended from the dome of the bell C, and is guided by a sleeve f secured at the lower end of the tube. At the upper end of this tube F, v

are provided several openings 7, for the passage of the exhaust steam. A number of tray-shaped vessels G, of slightly smaller diameter than the bell, are placed one above the other and built intothe bell C in such a manner that all of them will be covered by the water bath B, when the bell is in its lowest position, but that all of them will be above the surface of the water, when the bell stands in itshighest position, abutting against the stops a of the tank A. Still another pipe I-I, opening into the atmos phere, is provided in the bell C, and this pipe is given such a length,that its lower opening stands just above, the Surface of the water, when the bell C is in its uppermost posltion; but with the bell lowered, the plpe s passed into the water. If. there is a Specification of Letters Patent. I te te 1 1915;

greater quantity of exhaust steam than can be I consumed, the surplus of the exhaust steam passes through the pipe e ,tube F and openings 7 into the interior of the floating bell C. Supposing the latter to be situated in its upper middle position, only the lower I vessels Gr then stand below the surface of the water B, while the upper ones are filled with water and stand above said surface. In consequence of the contact of the exhaust steam with the cool upper surface of' the upper vessels G, and with the water bath B, as well as with the wallsof the bell O, a portion of the exhaust steam will be condensed. Any

still remaining surplus of exhaust steam will then cause the bell G to rise, whereupon also the lower vessels G, one after the other, will rise and ofi'er additional contact surfaces to the exhaust steam In consequence of the enlargement of the contact surfaces, the amount of condensation will a naturally be greater, so that generally an equilibrium soon will be reached, whereby the amount of condensed exhaust steam will be thesame as the amount supplied and consequently the bell does not rise farther. Under the supposition, that the exhauststeam supply is so great, that not all of the exhaust steam can be condensed, when all of thevessels G have been raised from the water bath B, the hell 0 will then rise until it strikes against the abutments or stops a In thisposition, the lower opening of the pipe II will be situated above the surface of the water, so that the surplus steam may escape through the pipe H into the atmosphere. Should more exhaust steam have to be consumed than what the exhaust steam main E is capable of supplying, additional steam will be drawn for the heat storing apparatus. Supposing now that the floating bell, to start with, is situated in its middle position. In consequence ofthe escape of the steam from the storing apparatus, the pressure under the bell C will diminish, and as a consequence a reevaporation, increasing the amountof steamwill take place, which evaporation is greatly favored by the large water surfaces of the vessels Gr situated above the water bath B. The bell, C will. simultaneously sink in consequence-of the diminishing pressure in the bell .C. The vessels G will then one after n 45' vention.

the other be passed" into the water bath B, water contained in the vessels, which hasbeen warmed by the previous absorption of condensed steam, now mixes with the cooler water in the tank A, whereupon the vessels, upon the subsequent rising of the bell C, will again contain cooler water.

The second embodiment of the present invention, see Fig. 2, distinguishes over the one first described simply thereby, that the vessels G have been replaced by a sprinkling device, which is constructed in the following manner: 'A number of annular vessels J andK are arranged alternately above each &5. other in the bell :C. The vessels J, which are provided with holes a in the side and bottom, are, seated on similarly perforated disks M, which in their turn lie on rods N, secured, in the bell C. The Vessels K are suspended from rods P, which are also secured'inthe bell C. Several pipes Q, distributed over the whole bottom surface, reach out from the bottom of the vessels K, and which are divided into two branches and 9 One of these pipe-branches 9 opens above a perforated annular plate R, secured tothe tube F and the other branch 9 opens above another perforated annular plate T, situated on a level with plate R, and secured on the cylindrical surface of the bell C. The manner of operation is substantially the same as in they first described embodiment. The water lifted by the vessels J and K, on the risingof the bell C, does, however, not remain therein, but flows instead gradually off through, the holes 2' furnished in thevessel J and through the pipes Q, attached-to the vessels K. In consequence of th e=perforations in the plates M, R and T, the flowing off water will be very finely distributed, whereby the exhaust steam, entering the bell C, will be condensed to a much higher degree, than what is the case inithe first described embodiment of the in- Anadvantage common to both ofwthese embodiments is, however, that the vessels, built into the bell C, resist any sudden rising of the bell and therefore provide a powerful brake for the bell against any 5o: shocks from the steam.
